[Qemu-devel] [PATCH v2 18/40] blockjob: Split block_job_event_pending()

[Kevin Wolf <kwolf@redhat.com>]

block_job_event_pending() doesn't only send a QMP event, but it also
transitions to the PENDING state. Split the function so that we get one
part only sending the event (like other block_job_event_* functions) and
another part that does the state transition.
